I'd like to see enhanced configuration and reporting available in WHM for disk space usage and bandwidth quotas.

In my current version of WHM (6.4.2), under

server setup > tweak settings

... I can turn on or off the reporting for 'Disk Space Usage Warnings' using the check box.

I'd like to see this reporting enhanced in the following ways:
1. I can set one or more % levels where warnings I sent - eg. 80% (first warning), 95% (critical warning), and 100% (totally full warning!)
2. On a per account basis I should have the option to decide to whom the warning gets sent
3. For each % level where a warning is sent, I should be able to specify the default message that is sent (I'd include more advice about what to do).
4. I'd even like to be able to specify whether or not to shut an account down when the max limit is reached.
